Do Mormons believe in the Trinity?
Latter-day Saints believe in the New Testament teaching that there is a Father, a Son, and a Holy Ghost, all three of whom are fully divine, then Latter-day Saints believe in the doctrine of the Trinity…However, mormons do not believe in the definition of the trinity formulated by the councils of Nicaea and Chalcedon and elaborated upon by subsequent theologians and councils–that God is three coequal persons in one substance or essence. They do not believe it, because it is not biblical.
